A VGA switcher is a device that can switch between multiple VGA signal sources and 1 VGA display device. VGA switch with 3.5mm audio refers to the addition of a 3.5mm audio interface on the basis of the VGA switch, which can realize the switching and output of audio signals and meet the needs of users for audio equipment.
The principle of VGA switcher with 3.5mm audio
The VGA video signal is an analog signal that can transmit high-definition resolution images, but cannot transmit audio signals. 3.5mm audio signal is an analog stereo signal, which can transmit high-fidelity sound, but cannot transmit video signal. VGA switch with 3.5mm audio is a multi-input, single-output video switching device that allows users to share a display and audio system among multiple computers or devices. It realizes the selection and switching of different input signals through internal circuits, so that multiple devices can share a display and sound system.
